 is formed by the above-noted depression. The recent expeditions

enable us to mark, roughly, contour lines on the inland ice. This 

 has been attempted in Figure 4, where the proportional heights of 



the two glacial centers appear 

 very plainly. 



The northern center of glaci- 

 ation is known from the follow- 

 ing expeditions: Peary, 1892 and 

 1895; Einar Mikkelsen, 1910; 

 Knud Rasmussen, 1912; J. P. 

 Koch, 1 913; Knud Rasmussen, 

 1917. Of these expeditions 

 Koch's is the most important, as 

 it crossed the ice cap very near 

 the place of its greatest eleva- 

 tion. This expedition therefore 

 gives a complete profile of the 

 northern center of glaciation. 

 All the other expeditions took 

 place in the border zone. 

 The southern Hmit of the center of glaciation is not known from 

 any expedition, but must presumably be situated slightly to the
